Damian Wayne, if he was nothing else, then he was one thing; the prince of Slytherin. He was the son of the Bruce Wayne, and Talia al Ghul, after all. He was wizard royalty, from his mothers side, and the son of the Minister of Magicks on the other.

He knew he could be arrogant and prideful, but, wasn't that what his house was known for? He had a reputation to uphold!

Damian had few allies, and fewer friends. He knew for a fact he was passed down his trust issues from his father, and chose to cultivate the absolute best possible allies near him (and Jon. He was an outlier.)
